An uncommon case of an infected ovarian endometrioma

Ovarian endometriosis is common, most often associated with other endometriotic lesions of the pelvis. Among the classic complications of endometriosis, secondary infection is described but rare. We report a very interesting case of an endometrioma cyst mimicking a tubo ovarian abscess. We describe our diagnosis and surgical management by laparoscopic approach. A case of a 32-year-old patient, with a history of surgery for ovarian and deep peritoneal endometriosis, who consulted urgently for pelvic pain syndrome in a febrile context. Emergency laparoscopic surgery showed secondary infection of the endometriosic cyst with the presence of pus. A right adnexectomy was performed. The postoperative follow-up was simple. Secondary infection of endometriomas is a classically described but rare complication. Severe endometriosis would be a risk factor for developing a tubo-ovarian abscess with an incidence of 2.3 % in patients with endometrioma. Laparoscopic endometrioma surgery has demonstrated its superiority beyond question, numerous trials have confirmed these data. The benefit is established in terms of pain, infectious risk, scarring, wall complications, adhesion risk, length of hospitalization, return to normal activity, thromboembolic risk and cost. Infection of an endometriosic cyst is an exceptional complication. It is necessary to emphasize the particularities of this surgery, namely careful dissection to avoid secondary lesions, particularly digestive. •Secondary infection of endometriomas is a classically described but rare complication.
